RAIN-WATER GUTOFF.

Specification of Letters Patent.

Patented Aug. 24, 1915.

Application filed .Tune 17, 1913. Serial No. 774,233.

To all whom it may concern Be it known that I, GRovER C. CRANDALL, a citizen of the United States, residing at San Antonio, in the county of BeXar and State of Texas, have invented a new and useful Rain-Tater Cut-Off, of which the following is a specification.

My invention relates to cut-offs for rain water spouts, and particularly to cut-olfs designed to automatically direct rain water through one out-flow pipe or another.

The object of my invention is to provide a cut-off by which the first flow of water from a roof may be directed down a waste pipe, thereby carrying oIl dust and dirt which may be lying on the roof and later to direct the rain water-now running cleaninto a clstern or water receptacle.

In the drawings, Figure 1 is a front elevation of my device, the casing being broken away at the upper end; Fig. 2 is a side elevation, with more than half of easing broken away; Fig. 3 is a sectional elevation of the tank.

1 represents a vertical pipe that leads from the eaves-troughs of a house and communicates with an enlarged pipe 2, which communicates at its lower end with a discharge-pipe, 3, for the impure water that runs from the roof at the beginning of a rain, and with a pipe, 4, that leads to a cistern to supply the latter with pure rainwater.

5 represents a rock-shaft j ournaled transversely below the pipe 2, and between the upper ends of the pipes 8 and 4.

6 represents a cut-off valve that is concave on its upper side and has its ends rounded. This valve is secured transversely on the rockshaft, the latter being located at the center thereof. On the outward extended portion of the rock-shaft 5, and secured thereto is the cross-arm 7, having eyes 8 at both ends thereof. The two eyes 8 as described, are provided in case that the pipes 3 and 4 are vice-versally attached to a house. Then the hereinafter described arm would necessarily be connected to the opposite eye, to that shown in Figs. 1 and 2.

Fastened to the one end of cross-arm 7, as shown, is the lower end of arm 9, preferably, centrally located as shown. On said arm 9 is the weight 10, to normally tilt the valve and cause the latter to cut off pipe 4 and connect the pipes 1 and 2, with the dirty water pipe 3. At the upper end of arm 9 is the eye connection 11, to an eye 12 on the lever 13. Centrally secured to the lever 13 is the small rock-shaft 14, an opening 15 in the casing 2 being provided for the up and down movement of the said lever. At the end of the said lever is fork 16, which has its ends pivoted to a tank 17. This tank is provided with a movable cone shaped head 18, having an opening 19. Over this opening and securely soldered is the screen 20, which prevents any dirt or trash from entering the tank 17 On the lower edge of the head and located preferably below the opening 19, is the arrow point 21. Directly on the upper end of tank 17 and in position as shown are the graduations 22. This combination is to provide means to adjust the amount of rain water taken into the tank, for the reason that roofs having greater or less surface would necessitate more or less waste water. In adjusting the tank for a lesser waste, the head 18 is turned to the right until the arrow point 21 points to the desired number of gallons to be wasted, or is turned to the left to increase the number of gallons waste. The tank 17 is provided with an opening 23 at its upper end, and a leak opening 24 at its lower end.- The said lower opening 24 is located at the top of a cone shaped means extending upwardly into the tank 17, as shown.

At the beginning of a rain the water from the roof is fouled with dust and dirt on the roof, and this impure water is directed by the valve out through the pipe 3. A portion of the water passes through the openings at the top of the tank, and from thence settles into the tank 17 in which it slowly accumulates until the weight of said tank overbalances the weight 10, when the valve is tilted to the opposite position of that shown by dotted lines in Fig. 1, thus cutting off the pipe 3 and directing the water from the pipe 2 into the pipe 4 to the cistern. The opening 24 permits the water to leak slowly from the water tank, but not so fast as it is supplied during the rain. hen the rain is over, the water in the tank leaks out until the weight on the arm overbalances it, when the valve is tilted to its initial position, ready to direct the first dirty water of the next rain away from the cistern, as before.

Having thus described my invention, I claim Y In a device of the class described, a casing having an inlet and spaced outlets, a valve mounted for movement to position closing either outlet, means normally holding the valve in position closing one of the outlets,

and means Within the casing having operative connection With'the valve and arranged for actuation to overbalance the same, the said means comprising a receptacle provided With a drain opening and provided in its top With aninlet opening, and a cap rotatably mounted upon the top and having a screened aperture, the cap being adjustable to vary the size of the opening in the said top of the receptacle.

In testimony that I claim the foregoing as my own I affixed my signature in presence of two Witnesses.
